Our Abpromise guarantee covers the use of ab40860 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 1 - 3 µg/ml. Detects a band of approximately 65 kDa (predicted molecular weight: 53 kDa). 65kDa band detected in rat brain lysate.
The observed molecular weight corresponds to earlier findings in literature with different antibodies (Porcella et al, Eur J Neurosci. 2000 Mar;12(3):1123-7. PMID: 10762343).

  • Anti-Cannabinoid Receptor I antibody (ab40860) at 1 µg/ml + Human Brain lysate (35µg protein in RIPA buffer).

    Predicted band size : 53 kDa
    Observed band size : 46 kDa (why is the actual band size different from the predicted?)
    Primary incubation was 1 hour. Detected by chemiluminescence.

Abcam guarantees this product to work in the species/application used in this Abreview.
Application Flow Cytometry
Sample Human Cell (synovial fibroblasts from osteoarthritic person)
Specification synovial fibroblasts from osteoarthritic person
Preparation Cell harvesting/tissue preparation method: cells were detached by accutase (PAA), spun and fixed in 4 % formalin for 20 min. Then, cells were spun and resuspended in 100 µl BD Perm/Wash solution containing 0,5 µg CB1 (ab40860). This was then incubated for 30 min at 4 degrees. Samples were washed with 1ml of BD Perm/Wash buffer and spun again. Then 100 µl of BD Perm/wash were added including 1 µl secondary antibody (donkey anti goat, Santa Cruz Biotech). This was again incubated at 4 degrees for 30 min. After another wash step, cells were resuspended in 4 % Formalin in PBS and analyzed.
Sample buffer: BD Perm/Wash, 4 % Formaldehyde in PBS
Fixation Formaldehyde
Permeabilization Yes - BD Perm/Wash
Gating Strategy fibroblast culture only
